SPECIFICATION forming part of Letters Patent No. 583,491, dated June 1,1897. Application filed OCtObST 24, 1896. Serial No. 609,979. (Nomodel.)

To all whom, it may concern:

Be it known that l, CHARLES S. LABOFIsH, a citizen of the United States,residing at Williamsport, in the county of Lycoming and State ofPennsylvania, have invented a new and useful Cyelometer, of which thefollowing is a specification.

My invention relates to cyclometers, and has for its object to provide adevice of this io class which is simple in construction and is adaptedto accomplish the registration of distance when applied to a vehicle,such as a bicycle, with the minimum number of operating parts andwithout the use of gearing for I5 communicating motion from oneregistering wheel or member to the next of higher denomination.

Further objects and advantges of this invention will appear in thefollowing descrip- 2o tion, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View. Fig. 2 is alongitudinal central section of the same. Fig. 3 is a similar viewshowing the registering-wheels in elevation. Fig. 4 is a transversesection on the line 4 4 of Fig. 2. Fig. 5 is a transverse section on theline 5 5 of Fig. 3.

3o Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates a cylindrical casing having one end open and fitted with aremovable head or cap 2, which in the construction illustrated isthreaded in the end of .the casing. This removable head or cap carriesan arbor 3, which is located axially in the casing, and upon it aremounted rotary registering members or wheels respectively designated bythe numerals 4, 5, G, and 7, bearing numerals for exposure throughinspection-openin gs S in the shell or casing and occupying suchrelative positions as to arrange the exposed numerals,

respectively, in the units, tens, hundreds, the., places. The unitsregistering member or wheel 4 is held from displacement by a terminalenlargement or head 9 on the inner end of the arbor 3, andthe wheels arespaced at 5o the desired intervals by means of interposed collars 10. Asuitable transparent shield 11 covers the openings S to prevent theaccess of dust and moisture to the interior of the casing.

Located exteriorly of the shell or casing is a star-wheel 12, adapted toreceive motion from the wheel of the vehicle, and to the spindle 13 ofthe star-wheel is fixed a driving-gear 14, having a smooth circularperiphery, except at one end, where it is provided with a 6o radial spuror tooth 15, the contiguous portions of the periphery upon oppositesides of said spur or tooth being cut away to form depressions 16.Arranged in operative relation with the driving-gear is a toothed pinion17, adapted to receive motion from the gear 14, and hence having itsteeth 17n located in the plane of the detent 15 for successiveengagement thereby. Hence each complete revolution of the gear 14 willadvance the 7o pinion 17 a distance equal to the interval between twocontiguous teeth 17, and in order to hold said pinion from accidentalmovement, as by the jarring of the device, the circular periphery of thegear projects into the paths of the contiguous teeth 17 or extendsslightly between said teeth. This forms a lock to prevent the movementofthe pinion, and the latter is only released when the notch ordepression 16, located contiguous to the spur Se 15, comes intoalineinent with the tooth which is about to be engaged by said spur. Assoon as the spur has advanced the pinion one step the circular peripheryoi the gear again locks the pinion against further movement until thegear has completed the next revolution. The pinion 17 also carries thespur 1S, which is designed for successive engagement with seats ornotches 1i) in the units-registering member or wheel 4, said seats ornotches be- 9o ing formed in the cross-sectionally iiat circular rim 4,which combines .with a web 20 to constitute the registering member orwheel. It will be seen that as the pinion 17 completes a revolution thespur 18 will engage one of 95 the seats or notches 19 and advance theunitsregistering member or wheel one step, or the distance betweencontiguous seats or notches.

1n order to accomplish the communication of motion from one registeringmember or ico wheel to the next of higher denomination, I preferablyconstruct the same with yielding 2 sesam webs 20, whereby the rims arelaterally resilient. This quality of the registering members or wheelsenables them to be moved to secure the engagement or interlockingof therims, the rim of each wheel of lower denomination being provided with alateral stud or projection 2l to engage one of a series of seats ornotches 22, formed in the rim of the adjacent wheel of higherdenomination. Hence by imparting lateral movement to the unitswheel itmay be brought into interlocking engagement (by neans of the stud 2l andone of the seats or notches 22) with the tenswheel to cause an advancemovement of the latter, and the means illustrated in the drawings foraccon'iplishing this lateral movement of the units-wheel includecooperating movable and fixed cams 2.5 and 2-t, carried, respectively,by the units-wheel and the shell or casing, and shown, respectively, inFigs. 2 and 3. lVhcn the units-wheel has completed one revolution, theprojecting cam 2S comes in contact with the cam 2land forces the rim ofthe units-wheel toward the tens` wheel sufficiently to cause theengagement of the stud or projection 2l with one of the notches 22, andhence while the movable cam is traversing the surface of the fixed camthe tens-wheel is moved forward one step, or a distance equal to theinterval between contiguous notches 22.

In order to communicate motion from the tens-wheel to thehundreds-wheel, it is necessary to lock the hundreds-wheel to thetenswheel long enough to secure the advance movement of the formerthrough a distance equal to the interval between contiguous numerals.The tens-wheel is provided with a stud or projection 2l for engagementwith seats or notches 22'L in the rim of thehundreds-wheel, but thecoactin g cams 23 and 24: are capable of moving the units-wheellaterally a sufficient distance only to secure the engagement of thestud 2l of the units-wheel with the seats or notches 22 of thetens-wheel, whereas it is necessary that motion should be communicatedfrom the units-wheel to the tens-wheel in order that the stud 2l may bebrought into engagement with one ot' the notches 22. In order toaccomplish this, I reduce the depth of one of the seats or notches inthe tens-wheel, as shown at 22h, the bottom of this shallow notch beingarranged out of the plane of the notches 22 and closer to the rim of thewheel il, whereby when the tens-wheel is about to complete onerevolution and the units-wheel is deflected laterally to interlock itsrim with that of the tenswheel the stud 2l engages the notch 22h, and aslthis notch is shallow the tens-wheel will also receive lateral movementsufficient te cause its rim to interlock with that of the hundreds-wheelby the engagement of its stud 2ln with one of the notches 22". In thesame way when the huinlreds-nf'heel is about to complete a revolutionthe forward motion of the hundreds-wheel is communicated thereto byreason of the engagement of the stud 2]. with a shallow or reduced notch22c in the humlreds-wheel.

Frein the above description it will be seen that motion is communicatedfrom one wheel to the next of higher denomination by reason of thelaterally resilient or yielding construction of the wheels, `which areprovided with rims having interlocking projections and dcpressions, saidprojections and depressions being brought into operative relation by thedeflection of the wheels from their normal positions, and the subsequentdisengagement of said rims to avoid communicating excessive motion beingsecured by the resilience of the webs 20.

ln order to prevent accidentaldisplacement of the registering members orwheels, l preferably employ a locking device consisting of a yieldingspring-actuated locking-pin 25, mounted in a cavity 2G in the arbor inthe plane of each wheel, to engage one of a 'series of notches 27 formedin the hub of the wheel.

It will be understood that in practice various changes in the form,proportion, and the minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the advantagesof this invention.

llaving described my invention, what I claim is l. In a cyclometer, thecombination with a plurality of coaxial registering members or wheelshaving transversely-resilient rims provided with interlockingprojections and dcprcssions, and means for detlecting the rim of eachmember or wheel of lower denomination to bring it into operativerelation with the rim of the contiguous wheel of higher denomination,substantially as specified.
